Step Potential
Step potential is the step voltage between the feet of a person standing near an energized grounded object. It is equal to the difference in voltage, given by the voltage distribution curve, between two points at different distances from the electrode. A person could be at risk of injury during a fault simply by standing near the grounding point.
Touch Potential
Touch potential is the touch voltage between the energized object and the...
The 25 kV Class 200 Ampere loadbreak separable insulated connector system didn't always have today's reputation for safety and reliability. As 25 kV Class loadbreak connectors increased in popularity in the 1980's and 1990's, utilities reported unacceptably high numbers of flashovers...
A comprehensive review of IEEE guidelines and documents BY JIM TOMASESKI, IEEE, NESC Main Committee, PAR Electric Every day, utility workers are risking their lives in work environments that involve high-risk activities such as working at extreme heights, managing or repairing energized...
Remote field operations present the safety organization with a myriad of challenges when it comes to ensuring the safety of the people that you send out to work in the field every day. Without a doubt, this includes the line workers, but it also includes nearly every member of the staff whose...
When working in close proximity to exposed energized equipment or working on live electrical circuits, it’s necessary to protect not only the equipment being worked on but also the worker. Rubber insulating gloves and insulated hand tools are vital components of a successful PPE system and...
A coalition of large energy consumers and ratepayer advocates has filed a complaint with the Federal Energy Regulatory Commission (FERC), urging the agency to prohibit transmission owners from independently planning "local" transmission projects exceeding 100 kilovolts (kV). The coalition argues...
In a significant shift, the Federal Energy Regulatory Commission (FERC) has decided to abandon its transmission incentives policy, particularly the construction work in progress (CWIP) incentives. This decision marks a pivotal change in how transmission projects are financed and regulated,...
Verifying the functionality and integrity of a grounding system is critical to maintaining a safe workspace. Unfortunately, the tests used to achieve this goal, as well as the standards used to assess them, have required a specialized skillset, often leaving these tests done improperly or not at...
For years, manufacturers of ground rods have strived to develop technical specifications for the electrical industry which address the specific needs and applications of clients and endusers alike. One reason for stressing the importance of this was to assure that the customer would receive what...
Taking care of your grounds and jumpers A lineman’s ground and jumper cables look and feel like they’re built to last forever, but looks can be deceiving. They get tossed in the truck, dropped in the mud, left hanging in the rain, and generally overlooked. With everyday use, we start...
